The Best GPT-trainer Alternative
GPT-trainer hands you the controls: choose the model, shape the prompt, wire the functions, assemble the agent. Asyntai is for the person who owns the website and wants it answering visitors today — give it your domain, choose the colours and the tone in plain language, publish.

Plain Language, Not a Model Console
Live Today, Without Building an Agent First
GPT-trainer is a builder platform, and that is exactly right when building the agent is the job you came to do. If the job is getting your website answering visitors, Asyntai asks for your domain, reads it, and puts a working chatbot on the page the same day — nothing to assemble, nothing to decide about models.
Answers From Your Content, With Nothing to Wire Up
There is no data source to connect, no retrieval step to configure and no function to define. Asyntai reads the pages, PDFs and policies you already publish and writes each reply from them, so answers stay in step with the site rather than with a knowledge base someone has to remember to refresh.
Settings You Can Read Without a Glossary
In a builder like GPT-trainer the model and the prompt are yours to choose, and that control genuinely matters when tuning the agent is the work. Asyntai keeps it out of the way: describe the tone you want in a sentence, set what the AI may and may not discuss, and watch a live preview answer while you type.
One Assistant for the Whole Site, Not an Agent per Job
Agent platforms invite you to build one agent per use case and route between them. Asyntai gives each website a single assistant that handles pre-sales, support and opening-hours questions from the same content, and one account covers the other sites on your plan.
Owned by Whoever Owns the Website
Colours, greeting, position, language and tone of voice are all clicks with a preview beside them. The person who publishes your pages can launch the chatbot, change its voice on a Tuesday afternoon, and never open a developer console to do either.

What You Get Without Building an Agent
A chatbot configured in plain language, live from your domain, answering from the content you already publish
No Model to Choose
There is no model picker, no temperature slider and no system prompt to engineer. You describe how the assistant should behave in ordinary sentences, and it replies to visitors in whatever language they write in.
Your Domain Is the Setup
Paste your address and the crawler collects your product pages, FAQs and policies by itself — 100 pages on Free, 500 on Starter, 1,000 on Standard, 5,000 on Pro. That is the knowledge step, finished.
One Snippet and You Are Done
Installation is a single line of JavaScript, the same on any platform. There is no SDK to import, no endpoint to call, and nothing to redeploy when you change a setting — edits take effect on the live widget.
What Changes When Setup Is a Conversation, Not a Build
No agent to assemble, no model decisions to defend, and a website that answers visitors from what it already says
A Finished Chatbot, Not a Toolkit
A builder gives you the parts and the freedom to combine them however you like, which is real value when the agent is the thing you are shipping. Asyntai gives you the finished article: one widget, your content, your colours, on the page.
Captures Leads While the Chat Is Open
Someone drifting towards the exit halfway through a chat gets asked for an email address or a phone number, worded to fit wherever the conversation has reached. A pre-sales question then survives as a contact rather than a bounce. The Starter plan carries it, and there is no form logic to build behind it.
Grounded in the Pages You Publish
Answers come from your own site, and where something is not covered the AI says so rather than filling the gap. Edit the page and the next answer follows — no re-indexing run to kick off, no prompt to patch.
Still in the Builder
Typical conversion while the site still has no answers on it
Answering Since This Morning
Conversion when visitors get an answer where they asked
* Based on industry studies showing instant chat replies can lift conversion by 20-40% compared with email or callback replies
Moving Over From GPT-trainer Takes One Sitting
No model selection, no prompt engineering, no flow to draw - three steps
Say What the Business Does
Give the AI a few plain sentences about who you are and how you want it to speak, plus anything the site leaves out — a price list, a returns policy, a PDF. Documents you already gathered for another bot come straight across as files. Ordinary language is the whole interface.
Point It at Your Domain
The crawler reads your pages and policies on its own. Nothing to connect, no retrieval settings to weigh up, no chunking decisions to make before you see it working.
Add the Snippet and Publish
Paste one line of JavaScript into your site and the widget appears on every page. Change a colour or the greeting later and it updates live, with nothing to rebuild and nothing to ship again.
